Bestechman Sprite Black-Purple G10, Black Stonewashed M390 – an ultralight EDC folding knife weighing only 45 g
The Bestechman Sprite Black-Purple G10, Black Stonewashed M390 (BMK21E) folding knife is an ultralight version of the Sprite that combines Böhler M390 steel with a Black-Purple G10 handle. With an overall length of 142.00 mm, the knife weighs a mere 45.00 g, making it practically invisible in your pocket.
The 60.00 mm blade features a Drop Point profile, a flat grind, and a smooth cutting edge. The black stonewashed finish complements the contrasting handle, while the B-Lock, double-sided thumb studs, and a reversible deep-carry clip ensure comfortable handling.
Böhler M390 61 HRC in an ultra-lightweight design
The blade is made of Böhler M390 steel hardened to 61 HRC. The use of this steel in a folder weighing just 45.00 g combines very low weight with high resistance to wear and corrosion.
Black Stonewashed and Drop Point Profile
The black stonewashed finish gives the blade a subdued look. The Drop Point profile and flat grind create a practical geometry for light, everyday cutting tasks.
Black-Purple G10 and a weight of just 45 g
The G10 handle in black-purple reduces the knife’s weight to 45.00 g. The B-Lock ensures ambidextrous operation, and ceramic ball bearings support the smooth action of the compact blade.
